Just from the pictures, I can see that the leather straps are frighteningly low quality "handmade" affairs. The watches are run-of-the-mill vintage offerings that can be bought from many places.
Also, I thought HMT was a bargain-basement indian brand, but they are asking high prices for them and the occasional russian.
I had never heard of them before. It looks like they just buy old watches, clean them up, change the strap and charge a premium. I would just buy a vintage watch anywhere, a tube of Polywatch and a nice band.
